Natural fuel use is increased due to industrial development and these sources oil, coal and natural gas reservoirs are limited. Energy crises need to search for alternate source of energy that is specifically renewable energy. Human power credit is more because of health benefit as a source of energy. More effective use of human power could be achieved through properly designed mechanisms. Human power as prime mover used to operate working unit is termed as human powered machine. Design considerations for bicycle mechanism are discussed in this paper. Owing to appropriate and most effective technology to use human power efficiently is bicycle technology. In bicycle technology operator uses mostly pedal to operate machine and transmits power through crank, chain and freewheels to the working unit. Bicycle is the main mode of transportation for many Indian villagers. Most of these villages are unelectrified. Power generated by pedaling can be converted from mechanical to electrical energy by using either dynamo or alternator. Keywords: Human Power machine, BicycleTechnology, Pedal ,Generator I. INTRODUCTION Energy is the driving force of modern societies, and generation and utilization of energy are essential for socioeconomic development. Per-capita energy consumption levels are often considered a good measure of economic development. In recent years, energy scarcity has become a serious problem due to depletion of non-renewable energy sources, increasing population, globalization of energy intensive economic development, environmental pollution, and global warming [3]. In this context, the field of renewable energy represents a new frontier for the academic and research community, due to the following factors: • Depletion or unreliability of non-renewable energy sources, e.g., oil • Environmental pollution, e.g., due to coal use • Needs of increasing population, especially in resource- scarce developing countries • Global Warming/Climate changes • New applications in modern, high-tech settings – e.g., wearable computing and portable consumer electronics While in developed countries the energy problem is one of short-term scarcity or optimum use, an estimated 40% of the worldǯs population – or, 2 billion people mainly in the less developed countries – do not have even have access to electricity. Moreover, this number is expected to double by the year 2050. The reasons for this limited access to electricity in developing countries are the lack of energy sources such as coal, oil, or nuclear energy, and – even where such sources exist – the lack of expensive capital to exploit existing resources. While the costs of renewable energy sources such as solar and wind energy are falling gradually, these technologies are still far too expensive for developing countries, where about half the population has incomes of less than two dollars a day. In recent years, there have been many interesting developments in the field of human power conversion. In the present paper, a method of harnessing the power of children's play in playgrounds and public places, on devices such as the seesaw, merry-go-round, and swing is proposed. Data for 24 people, aged from 16 to 61 years old, riding a bicycle for 17 km (10 miles) were recorded and analyzed. During data logging procedure the average power of a biker varied between 215W to 375W. The graph in Fig. 1.1 shows the maximum duration of human effort for different levels of power. From this graph one can observe that healthy humans‖ can sustain approximately ͹ͷW ȋͲ.ͳhpȌ for a full 8-hour period, while ―first class athletes‖ can sustain approximately 300W (0.4hp). And that is for a single (stationary) bike; they are 20 times larger for a medium-sized gym with 20 bikes. We believe these numbers are promising and justify an attempt to harvest (part of) this energy efficiently [1].
